Review, document, and fix up Regions-in-Transition timeout logic
----------------------------------------------------------------

                 Key: HBASE-3181
                 URL: https://issues.apache.org/jira/browse/HBASE-3181
             Project: HBase
          Issue Type: Improvement
          Components: master, regionserver, zookeeper
    Affects Versions: 0.90.0
            Reporter: Jonathan Gray
            Priority: Blocker
             Fix For: 0.90.0


In some of the testing Stack and I have been doing, we've uncovered some issues with concurrent
RS failure and when the Master is under heavy load.  It's led to situations where we handle
ZK events far after they actually occur and have uncovered some issues in our timeout logic.

This jira is about reviewing the timeout semantics, especially around ZK usage, and ensuring
that we handle things appropriately.
